when you imagine music, is it like a little tape playing in your head? >> yes, it is. and it works the other way, from the point of view from the composer, trying to compose something. i might be sitting on an airplane and i will remember some experience. let's say running with anticipation, or something you saw. maybe you saw something spectacular, an illusion of light or something, and it creates an image. i will try to read something done quickly because i am trying to capture one that is. and of course, that stuff is very fleeting. the other thing, musicians who played the guitar, something with your fingers, they feel as

if they are remembering in their fingers. oftentimes, you play a passage and you cannot think your way through it. your fingers have to play the way through it. muscle memory. from a scientific standpoint, if i were to scoop your brain out of your head, your fingers would not remember, but there is a motor cortex that remembers the sequence. there is a whole field that studies the sequence, how one movement is remembered in a succession of a sequence. >> the process of creating, trying to start creating music is not that different for me that it is remembering music. it is revoking some kind of image or movement. -- evoking some kind of image or movement. >> can i ask, i am a musician,

do you have any advice -- often have trouble losing -- moving away from my everyday and getting into music. do you have any recommendations on how to speed up that context switching? >> i am assuming that as a professional musician, he doesn't have to do with complicated problems. >> you would not want me doing that. believe me. >> still, you have the context switch of being creative, non creative. >> that is true. sometimes you need something to wipe the slate clean. it could be taking a walk. these days, disconnecting. i have a studio. when i go there, is a place to work, i did not need to take my cell phone out there. having a physical location you can go to -- this is where i do

this -- even just a quarter of your room. >> from a cognitive neuroscience standpoint, if you dedicate a place, if you are religious about it -- or clock 30 i am going to spend an hour -- 4:30 i'm going to spend an hour here or there. that contextual aspect helps. inform is now wrapping up all of our events by asking our speakers, ourselves included, the following question. alex, what is your 60-second the idea to change the world? >> i think everybody should listen to music from other cultures. even daniel has said that, you know, we need to have that in

printing when we are young to understand balinese monkey chants or something to put it into context. i travel a lot. i just came back from asia. i was given a lot of career in music, a lot of ethnic music -- a lot of korean music. even though you may not have a cultural context, if you give it a little bit of a chance, it is an opportunity to open up your mind a little bit. when you do that, it may on sub -- some subconscious level give you a better understanding of why people are the way they are in different parts of the world and who they are. i think we should all be listening to each other's music and all try to play a little bit of music or sing. i think it is -- yeah. 60 seconds there? [applause]

>> and you, daniel, what is your 60-second idea? >> as an educator and teacher, i think my 60-second idea to change the world is better education. if we could teach the next generation of kids to be critical thinkers, just not accept what they are told but to decide for themselves, to give them the tools to make informed decisions about what is right and what is not, about what has been established and what is just here say, what really has a grounding in fact versus rumor, i think the world would be a much safer, more peaceful, and more prosperous place. [applause] >> let's get a big, final round of applause for this nice, informed foray into neuroscience and music with myself, daniel levinson, and the great guitarist and composer, alex

degrassi. now, this meeting of in forum and the commonwealth club is adjourned. [applause]
